Abstract

Provided is a communication terminal device which performs audio encoding by using downloaded audio codec while using an existing radio communication system infrastructure, a channel codec, and an error correction/detection function as they are. In the communication terminal device, if a judgment unit (103) judges that the number of bits of audio codec software downloaded from a distribution codec storage unit (161) of a base station device (160) is equal to or smaller than the number of bits of the corresponding encoding parameter of audio codec software inherent to the terminal, a codec control unit (104) encodes audio inputted from a microphone (105) by using the audio codec software downloaded from the distribution codec storage unit (161).
